A trading journal is a record of your trades and the decisions around them. A broker statement tells you what filled. A useful journal also preserves why you entered, what you planned to risk, and what you did when the trade changed. Start small enough that you will keep doing it.
Start with one repeatable record
You do not need a complicated scoring system or a long essay after every trade. Start with your next completed trade. Record the facts first, then add a sentence about your decision while you can still remember it.
A spreadsheet can work. An app can make the calendar and calculations easier. The important part is recording the same information consistently, not choosing the most elaborate tool.
- Instrument, direction and quantity: what you traded, long or short, and how much.
- Entry and exit prices and timestamps: when the trade actually happened, not when you wrote the note.
- Fees and net result: check the result against your broker, especially for partial fills or options.
- Setup and original risk plan: the reason for entry, planned stop or invalidation, and intended exit.
- What you actually did: changes to the plan, the reason for each change, and one question for review.
Separate the plan from the hindsight
Before entering, write something you could check later: “I will wait for the pullback before entering. If the setup fails, I will use the exit I planned.” Avoid changing your original explanation after seeing the result. If your thinking changes, add a new note rather than rewriting what you knew beforehand.
After closing, describe the action rather than labeling yourself. “I entered before confirmation” is reviewable. “I am bad at trading” is not. A profitable trade can break your rules, and a losing trade can follow them. Record process and outcome separately.
| Too vague to review | A decision you can revisit |
|---|---|
| Bad trade. Need more discipline. | Entered before my planned confirmation. Next review: did other early entries also depart from the setup? |
| Good trade. Made $40. | Net result +$40 after fees. Moved my planned stop once; review that decision separately from the profit. |
Keep a short record of the day, too
Sleep, stress and focus can be hard to reconstruct on Friday. Record them at a consistent time instead. A quick rating or a yes/no habit such as “Followed my preparation routine” is enough to begin. Use definitions that mean the same thing to you from day to day.
Do not choose a rating to explain a loss after the fact. If you did not log a day, leave it missing rather than inventing a memory. Notes can supply context that a number misses: interruptions, a changed schedule, or why you deviated from your plan.
These records are observations, not evidence that a habit caused a trading result. Their first job is to preserve context for a later review.
Review once a week with three questions
Pick a manageable review period and check that its trades are complete. For a review of realized results, use closing dates consistently; a trade opened last week and closed this week belongs in this week's realized outcome review. Keep still-open positions separate.
Read individual notes before deciding what a summary means. If one unusually large win makes the week positive, that tells a different story from many similar-sized wins. Check costs, instruments and trade sizes before comparing days.
- What happened? Check net P&L, wins and losses, and how much one trade influenced the total.
- What did I do? Find one decision that followed the plan and one that needs a closer look.
- What will I observe next? Choose one specific question, such as whether early entries keep appearing, rather than changing five things at once.
